The latest egg-freezing startup, Cofertility, is offering a strange deal: freeze your eggs for free, but in exchange, you'll donate half to prospective parents.

The company’s CEO, Lauren Makler, has a motto: 'The best time to freeze your eggs is when you can least afford it.' But in the US, you can't freeze eggs for free; instead, young women like Sue, a viola player from Chongqing, are using their eggs to help others have babies.

Cofertility’s 'Split' program is not just about freezing; it’s about sharing. Donor-freezers can choose between the 'Fresh' or 'Frozen' models. The former involves one cycle, while the latter, involving two cycles, means you donate your first batch to the eager.

The market for fertility tech is booming. Startups are using AI to predict conception probabilities, and established clinics are being bought out by private equity. Cofertility stands out with its unique intervention, blending biohacking with social engineering.

The pressure to reproduce has evolved into a biohacking imperative. Young, career-focused women are taking charge of their future fertility. But is this the kind of future we want? Cofertility’s approach to egg donation and sharing feels like a mix of sci-fi and social media.
